#Requires -Module Pester
<#
.SYNOPSIS
    Pester 5 tests for cluster config and management cmdlets:
        Get-PveClusterStatus, Get-PveClusterNextId, Get-PveClusterOption,
        Set-PveClusterOption, Get-PveClusterConfig, Get-PveClusterConfigNode,
        Add-PveClusterConfigNode, Remove-PveClusterConfigNode,
        Get-PveClusterJoinInfo, Add-PveClusterMember, New-PveCluster.

    All tests are fully offline — no live Proxmox VE target is required.
